11427508970 BMW Oil Filter Housing Gaskets | OEM Leak-Proof

Real-world review: BMW oil filter housing gaskets that don’t quit

If you’ve ever chased a stubborn oil weep down the front of an E-series engine, you already know why the 11427508970 BMW - OIL FILTER HOUSING GASKETS matter. I’ve seen techs swap sensors, clean pulleys, even blame the valve cover—only to discover the filter housing gasket turned glass-hard from heat cycling. This specific reference fits a long list of BMWs: E81, E82, E87/E87 LCI, E88, E46, E90/E90 LCI, E91/E91 LCI, E92/E92 LCI, E93/E93 LCI, E60 LCI, E61 LCI, X1 (E84), X3 (E83/E83 LCI), Z4 (E85). Left-hand or right-hand drive? Doesn’t matter—it fits both.

These are new, original-condition parts manufactured in JULU INDUSTRY AREA, XINGTAI CITY, HEBEI PROVINCE, CHINA 055250. In practice, what owners tell me is simple: install once, torque to spec, and stop smelling hot oil after a long commute. To be honest, that’s all most of us want.

How they’re made (and tested)

Process flow: compound mixing → compression molding → flash trimming → post-cure → dimensional inspection → oil immersion test → leak/pressure test → packaging. Methods follow automotive QA routines: PPAP/CPK sampling where required. Testing includes ASTM D471 oil swell (ACEA A3/B4 5W-30) and ASTM D395 compression set.

Oil swell (ASTM D471): < 5% after 70h @ 100°C.
Compression set (ASTM D395B): < 25% after 24h @ 150°C.
Pressure leak test: no seepage @ 6 bar for 30 min on aluminum housing.
Dimensional tolerance: ±0.10 mm on critical sealing ribs.

Where these gaskets shine

Use cases I see most: preventative maintenance during belt/alternator service; after a persistent front-block oil mist; and any time the housing is off for cooler/thermostat work. Independent shops like them because the sealing bead geometry is consistent, so you don’t chase comebacks. DIYers like that they seat properly without sticky sealants.

Vendor comparison (field-notes)

Vendor	Material quality	Certs	Lead time	Warranty	Notes
OEM BMW Genuine	FKM, very consistent	OE supply chain	Dealer stock	Dealer policy	Pricier; impeccable fit
YJM SEAL (this part)	FKM/HNBR, ≈ OE hardness	ISO 9001, IATF 16949	Stock or short build	12 months typical	Value/quality sweet-spot
Generic marketplace	Varies; sometimes NBR	Often none	Fast	Limited	Watch for shrink/hardening

Customization and bulk options

Material tuning: FKM vs HNBR based on climate and oil chemistry.
Hardness: ≈ 68–78 Shore A; color-coded batches on request.
Private-label packaging, laser code, and QR traceability.

Quick case notes

Fleet E90 320i taxis (120k–160k km): after switching to 11427508970 BMW - OIL FILTER HOUSING GASKETS, oil mist on the serpentine path dropped to essentially zero over 18 months. One shop owner told me, “Surprisingly drama-free. No comeback since the change, which is rare on these.” I guess that’s the point—fit it and forget it.

Installation tip: clean both aluminum mating faces, inspect for nicks, torque to BMW TIS spec in a crisscross pattern, and recheck after a heat cycle. No extra sealant needed.
